Key execs leave Plug Power in restructuring

Fuel cell manufacturer Plug Power Inc. announced a series of executive changes today, including the resignations of its president and the chief financial officer.

The Latham-based company said Jean Nelson resigned as CFO for personal reasons. She had only joined the company in October, filling a post vacated by the resignation of the previous CFO.

“Her resignation was solely her decision and a surprise to us,” CEO Roger Saillant said.

The company also announced that President Gregory Silvestri resigned. Silvestri had been named president in May, a job that Saillant had previously held. Silvestri had been chief operating officer.

Saillant said he would now reassume the duties of president, which includes oversight of the company’s day-to-day operations. A Plug spokeswoman said Saillant took back the duties of president to return to a more traditional management structure
